After nearly 19 years of comedy, Jay Leno will say goodbye to The Tonight Show on Feb. 6. To commemorate his final days as host of the late night comedy show, NBC decided to take a look back at some of the most memorable celebrity moments of Leno’s career.

The montage spans years of Leno’s stint on The Tonight Show, and treats fans to clips of some of the show’s biggest celebrity guests. Keep an eye out for a pre-teen Lindsay Lohan, Jerry Seinfeld stuck in a burlap sack and an uncomfortable moment involving Oprah and a finger-full of cake frosting.

After Leno’s final appearance as host on Thursday, he will hand the show over to its new leader, Jimmy Fallon, who has hosted NBC’s Late Night since 2009.

In the days leading up to Leno’s final show, Fallon has made appearances on The Tonight Show in preparation for the hosting transition. Fallon even brought one of his recurring Late Night segments, titled “Thank You Notes,” on Leno’s show to thank him for his guidance.

Leno’s final episode will air at 11:35 p.m. ET on Feb. 6, and will feature Billy Crystal and Garth Brooks.
